Thanks for the response!
Following (without /\glissando/) works now:
#{ \afterGrace #starttone { \once \hide Stem \parenthesize #endtone } #}
Unfortunately, as soon as I insert the /\glissando/ between /#starttone/
and /{/, it seems to ignore both /\afterGrace/ and /\glissando/,
shifting back all the following music.
How can I correct this?
Greetings,
Jonathan

Good day,
following snippet I need very frequently (with different notes instead
of c4 and e4):
\afterGrace c4 \glissando {\once \hide Stem \parenthesize e4}
That's why I wanted to create a music function to shorten the
expression. My previous attempt:
graceGliss =
#(define-music-function
(starttone endtone)
(ly:music? ly:music?)
#{
\afterGrace #starttone \glissando {\once \hide Stem
\parenthesize #endtone}
#})
doesn't work, Return Code 1.
In order to test the general functioning of define-music-function, I tried:
graceGliss =
#(define-music-function
(starttone endtone)
(ly:music? ly:music?)
#{
\afterGrace #starttone #endtone
#})
which works, what leads me to believe that the error must have something
to do with the curly brackets {} …
For some help I'd be very grateful!
Kind of stupid, but Scheme syntax is very simplistic (almost anything
except for parentheses needs to be space-separated) and your problem
here is that # goes into Scheme.
So you call upon one Scheme variable endtone} which does not exist. Put
a space before the closing brace.
